Description
Technical field
The utility model relates to a kind of pneumatic type lubricating grease charging machine, in particular, relate in particular to a kind of can be simple, fast and easy complete the pneumatic type lubricating grease charging machine that pumping unit is respectively maintained to the injection of position lubricating grease.
Background technique
Current generally uses pressure bar type greaser to pumping unit injection butter, and the major defect that this greaser uses has: cumbersome to gun barrel dress lubricating grease, and inconvenience, speed is slow; During shot lubrication fat, also waste time and energy, thereby rate while having influence on the oil recovery of pumping well also can cause the well of lying when serious.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of pneumatic type lubricating grease charging machine.
Pneumatic type lubricating grease charging machine of the present utility model, comprises that inside is the filling cavity of cylindrical cavity, and the two ends of filling cavity are respectively arranged with front sealing gland and rear sealing gland; Its specialization is: on described front sealing gland, be provided with the injection head communicating with cylindrical cavity, be provided with the air supply pipe communicating with cylindrical cavity on rear sealing gland, the end of air supply pipe is provided with gas quick connecting valve; In described cylindrical cavity, be provided with double-vane piston, on the outer surface at double-vane piston two ends, be provided with O-ring seals.
The inside of filling cavity is cylindrical cavity, for storing lubricating grease; Injection head, air supply pipe are individually fixed on forward and backward sealing gland, and cylindrical cavity can be connected with the external world by injection head and air supply pipe.Lubricating grease charging machine is connected with source of the gas by gas quick connecting valve, when entering the gas pressure of cylindrical cavity when higher, can order about double-vane piston and move towards injection head one end, for shot lubrication fat; When the air pressure entering is lower, can force double-vane piston towards rear sealing gland one side shifting, for sucking lubricating grease.
Pneumatic type lubricating grease charging machine of the present utility model, is provided with switch valve on the air supply pipe between described gas quick connecting valve and rear sealing gland.Control by switch valve to air supply pipe on off state, can control the amount that lubricating grease sucks and discharges.
Pneumatic type lubricating grease charging machine of the present utility model, described filling cavity is plexiglass transparent pipe, the periphery of filling cavity is provided with lubricating grease cleaner.
The beneficial effects of the utility model are: lubricating grease charging machine of the present utility model, by the two ends at filling cavity, injection head and gas quick connecting valve are set, in the cylindrical cavity of filling cavity, double-vane piston is set, under the effect of extraneous bleed pressure, quick suction and the injection of lubricating grease have been realized, efficiency is high, easy to operate, has reduced working strength.By switch valve is set on air supply pipe, can control the amount of the lubricating grease that sucks and inject; By the periphery at filling cavity, lubricating grease cleaner is set, can easily the lubricating grease that sticks to filling chamber outer surface be removed.
Novel in design, easily manufacture, with low cost, easy to operate, time saving and energy saving, safe and reliable, realize the replacing use of lubricating maintenance and the sealing pump housing lubricant oil of on-the-spot You Liangshi pumping unit, have a extensive future.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is structural representation of the present utility model.
In figure: 1 filling cavity, 2 cylindrical cavities, 3 front sealing glands, 4 injection heads, 5 rear sealing glands, 6 switch valves, 7 gas quick connecting valves, 8 double-vane pistons, 9 O-ring seals, 10 lubricating grease cleaners, 11 air supply pipes.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, provided sectional view of the present utility model and structural representation, it comprises filling cavity 1, front sealing gland 3, injection head 4, rear sealing gland 5, switch valve 6, gas quick connecting valve 7, double-vane piston 8, lubricating grease cleaner 10 and air supply pipe 11; The inside of shown filling cavity 1 is cylindrical cavity 2, and filling cavity 1 can adopt plexiglass transparent pipe.Front sealing gland 3, rear sealing gland 5 are arranged at respectively in the both ends of the surface of filling cavity 1, and injection head 4 is arranged on front sealing gland 3, and cylindrical cavity 2 is connected with the external world by injection head 4.Air supply pipe 11 is arranged on rear sealing gland 5, and cylindrical cavity 2 is connected with the external world by air supply pipe 11.
Double-vane piston 8 is arranged among cylindrical cavity 2, and the outer surface at double-vane piston 8 two ends is provided with O-ring seals 9, to realize the sealing between double-vane piston 8 and filling cavity 1 inwall.The end of air supply pipe 11 is provided with gas quick connecting valve 7, to realize with the quick of source of the gas, is connected.On air supply pipe 11 between gas quick connecting valve 7 and rear sealing gland 5, be provided with switch valve 6, switch valve 6 can adopt spherical valve.By switch valve 6, can open and turn-off air supply pipe 11, to control the amount of the lubricating grease that sucks and discharge through injection head 4.Lubricating grease cleaner 10 is arranged at the periphery of filling cavity 1, the cavity that central authorities match for filling cavity 1, and under the effect of external force, lubricating grease cleaner 10 can move along the axial direction of filling cavity 1, to remove the lubricating grease of filling cavity 1 outer surface.
In the process of using: when needs suck lubricating grease, lay down injection head 4, the front end of filling cavity 1 is inserted in lubricating grease, by gas quick connecting valve 7, connect source of the gas, exhaust reduces space air pressure, and double-vane piston 8 is sealing gland 5 one side shiftings backward, and then sucks lubricating grease; Recycling lubricating grease cleaner 10 is removed housing surface grease; When needs are got lubricating grease, load onto injection head 4, by connecting source of the gas toward injecting gas in space, increase air pressure, pressure is increasing, and double-vane piston 8 forward sealing gland 3 directions moves, and then gets lubricating grease.Whole filling process can be known by the transparent cavity of plexiglass and observes, and control injection amount by ball-type switch valve.
